Description

[Detailed description of the invention] [Industrial field of application and overview of the invention] This invention consists of a large number of continuous adhesive tapes, one side of which is coated with a release piece (hereinafter referred to as tack), which has an adhesive layer formed on the front and back sides. This relates to a tack continuum that has been made with a double-sided adhesive tape, and is easy to handle by changing the adhesive strength on the front and back sides of the double-sided adhesive tape and making cuts of different depths and directions in the adhesive tape and the mount to which the adhesive tape is attached. tack can be obtained from the above tack continuum.

[Prior art and its problems] An example of this kind of tack continuum is shown in FIG. 8.

This is a peelable piece 21 on one side of the double-sided adhesive tape 1.
The tack 4 as shown in FIG. 9, which is coated and pasted, is pasted and arranged in parallel on a strip-shaped mount 3, and the mount 3 has a first cut 30 extending in its longitudinal direction. A long and narrow strip-shaped body located between the first notch 30 and one side edge of the mount 3 serves as a first release strip 31 .

When using the above-mentioned tack continuum A, first peel off the first release band 31 on the mount 3 side, expose the adhesive surface of the double-sided adhesive tape 1 on the peeled trace, and then
1 together with the exposed adhesive tape,
This is peeled off from the top of the mount 3 to form a tack 4 as shown in FIG. After that, the tack 4 in this state is attached to the object to be joined, the peeling piece 21 is peeled off, and another object to be joined is placed on the adhesive surface of the double-sided adhesive tape 1 exposed at this peeling mark, so that the object can be joined. Two objects to be joined are attached to each other.

With this product, the tack 4 can be peeled off from the mount 3 according to the above procedure and used as required.

However, the tack continuum A has a problem in that it is inconvenient to handle the tack 4 separated from it.

This is Tak4 to join two objects to be joined.
When attached to one object to be joined, the peelable piece 21
This is because the peeling work cannot be easily performed.

That is, in the tack 4 separated from the conventional tack continuum A, one side of the double-sided adhesive tape 1 is entirely covered with a peelable piece 21 of the same size, and the tack 4 in this state is applied to the object to be bonded. This is because when pasted, the edge of the peelable piece 21 must be peeled off from the double-sided adhesive tape 1 by rubbing the periphery of the peelable piece 21, and the pasting operation cannot be performed quickly.

[Technical Problem] The present invention is based on the following problem: ``A tack in which one side of the double-sided adhesive tape 1 is coated with a release piece 21 is continuously pasted and arranged in parallel in the longitudinal direction on a strip-shaped mount 3.
A tack continuous body in which a first notch 30 is formed in the longitudinal direction thereof and has the same depth as the thickness of the mount 3.
In order to facilitate the handling of the tack 4 taken out from the tack continuum A, when taking out the tack 4 from the tack continuum A, the peeling piece 2 of the tack 4 is removed.
First, the technical problem is to form a knob that facilitates the peeling.

[Means] The technical means of the present invention for solving the above problems is as follows: ``Toward the strip-shaped mount 3 side, in the longitudinal direction thereof, and from the surface of the mount 3 to the boundary between the double-sided adhesive tape 1 and the release piece 21. In addition to forming the second cut 32 in depth, the adhesive force of the adhesive layer located on the mount 3 side of the double-sided adhesive tape 1 is made stronger than the adhesive strength of the adhesive layer located on the peelable piece 21 side. .

[Effect] The above technical means works as follows.

Of the adhesive layers on the front and back sides of double-sided adhesive tape 1, mount 3
Since the adhesive layer on the side has stronger adhesive force than the adhesive layer on the side of the release piece 21, the double-sided adhesive tape 1
The peeling piece 21 is more strongly attached to the mount 3 side.

Therefore, the side edge of the tack continuous body A and the second notch 32
When the backing paper 3 portion (hereinafter referred to as the second release band 33) between the 2 peeled off together with the peeling band 33,
The peeling piece 21 is exposed at the peeling trace, and this exposed portion becomes a knob portion.

After that, as in the conventional case described above, the first part of the mount 3
When the tacks 4 and 4 are separated using the notch 30, a part of the peeling piece 21 has a knob portion that protrudes from the double-sided adhesive tape 1, that is, a knob portion that facilitates peeling off the peeling piece 21. This means that the tack 4, 4 can be removed.

[effect] The present invention has the following unique effects.

Since the tack 4 taken out from the tack continuum A is formed with a knob that facilitates the peeling off of the peeling piece 21, the tack separated from the tack continuum A can be easily handled.

In addition, in the double-sided adhesive tape 1, since the adhesive force of the adhesive layer located on the mount 3 side is made stronger than that on the peeling piece 21 side, when the second peeling band 33 is peeled off, the second peeling band 33 The double-sided adhesive tape 1 located in the area is naturally peeled off together with the second peeling band 33, and there is no fear that it will remain on the peeling piece 21 side. Therefore, when separating the tack 4 from the tack continuous body A, the grip portion of the peeling piece 21 can be easily formed on the tack 4.

[Example] Next, an example of the present invention described above will be described in detail with reference to the drawings.

The tack continuum according to the embodiment of the present invention is constructed as shown in FIG. They are adhered and continuously disposed on a strip-shaped mount 3, and a first cut 30 having the same depth as the thickness of the mount 3 is formed in the mount 3.
Further, a second cut 32 parallel to the first cut 30 is formed on the mount 3 side, and the depth of the second cut 32 is set so that the double-sided adhesive tape 1 can be peeled off from the surface of the mount 3. The depth is up to the boundary of the piece 21. A portion of the mount 3 located between the second notch 32 and one side edge of the tack continuous body A becomes a second release band 33.

In addition, in the double-sided adhesive tape 1 covered with the front and back peeling pieces 21 and the mount 3, the adhesive strength of the first adhesive layer 10 facing the peeling piece 21 side is higher than that of the second adhesive layer facing the opposite mount 3 side. It is set smaller than that of 11.

In addition, when actually forming the tacks 4, 4 on the mount 3, first affix the strip-shaped double-sided adhesive tape 1 on the mount 3, cover the entire surface with a separator, and It is sufficient to form a large number of third cuts 20, 20 (having a depth that reaches the boundary between the double-sided adhesive tape and the mount 3) in a direction perpendicular to the above.

When using the double-sided adhesive tape 1, from the strip-shaped tack continuum A shown in FIG.
Peel off the 3 bands.

In the double-sided adhesive tape 1, the second adhesive layer 11 side with strong adhesive force is in contact with the second release band 33, and the other first adhesive layer 10 side with weak adhesive force is in contact with the release piece 21 side. As the second release band 33 is peeled off, only the portion of the double-sided adhesive tape 1 that has come into contact with the second release band 33 adheres to the second release band 33 side and peels off. Peeling piece 2 on the peeling trace
1 is exposed. This exposed portion becomes the knob portion 22 (see FIG. 3).

Next, the portion of the mount 3 located on the side of the first notch 30 and the second notch 32, that is, the first peeling band 31, is peeled off to expose the double-sided adhesive tape 1 at the peeled trace, and then the double-sided adhesive tape 1 is exposed as shown in FIG. As shown in Figure 2, pinch the double-sided adhesive tape 1 and release piece 21 and take out the tape 4 as shown in Figure 2.

In this Tactic 4, the double-sided adhesive tape 1 is in such a state that the second adhesive layer 11 with strong adhesive force is exposed, and the other side, the first adhesive layer 10 side with weak adhesive force, is covered with a peelable piece 21. It's getting old.

As shown in FIG.
Peel off piece 2
1 is peeled off, and then this display label B is pasted on a display product C (an article to be bonded where it is not desirable for the double-sided adhesive tape 1 to remain when the display label B is peeled off later) (see FIG. 6).

In this display label attachment state, the double-sided adhesive tape 1 has the first adhesive layer 10 side with weaker adhesive force attached to product C, and the other side with stronger adhesive layer 11 attached to display label B. It is in an attached state.

Next, when display label B is peeled off from this state, as shown in FIG. , and is peeled off together with display label B.
